摘要鑄造用砂熱膨脹性測試裝置，由加熱裝置、溫控裝置、移位傳感器、記錄儀等組成，可實現鑄造用原砂（亦可用於粘土型砂、水玻璃型砂、樹脂型砂等）的隨溫和等溫熱膨脹性測試。 -
For foundry sand from a famous domestic area, the curve of thermal expansivity with the temperature was described
本文最後給出了利用本裝置測得的國內某著名鑄造用原砂的熱膨脹溫度曲線。 -
Based on the object - oriented technique, this study defines four types of geographical event, i. e. expansivity, contraction, rebirth and vanishment events for management of land use data. and it further designed an object - superposition data updating model based on the land use feature of point, line and polygon ， which would take the advantage of the gis overlay function to effectly implement of updating spatial and attribute data
從面向對象的方法入手，定義了引起土地利用變化的擴展、收縮、新生與消亡四種地理事件，並分別按點狀地物、線狀地物和面狀圖斑的土地利用實體特徵設計了對象疊加更新模型，從而能利用gis強大的空間分析能力，來有效地實現空間數據和屬性數據的一致性更新。 -
In the second chapter, the conceptions of solids - - - - - - - structure, compressibility, expansivity, specific heat capacity, bulk modulus, and some nonlinear parameters are reviewed and elaborated. the basic theory in the broad sense and polynomial forms of eoss are stated
